1 x 400W Class D Mono Audio Amplifier Board Compact - TAS5630B For Subwoofer

Description

1 x 400Watt Class D Audio Amplifier Board Compact -TAS5630B(AA-AB31314)
Overview:
Here comes the compact version of the original TAS5630B 1 x 400W (AA-AB31314).
With the PCB size reducing down to 4.8inch x 3.6inch and robust performance, AA-AB31314 is competent to work as the part of the space contrained and high power density audio system.
Hear your music like never before with 400 Watts per channel of audiophile-grade TAS5630B includes a quiet running fan to keep things cool.
Besides of built-in chip protection, ESD and spike protection components used throughout input and output of the amplifier board ensure its robustness and reliability.
This amplifier board supports mono amplification by using PBTL topology.
Fan works when the temperature of heatsink reaches up to 45 degrees Celsius and stops when the temperature reduces down to 40 degrees Celsius.
So the audible noise and idle power loss brought by fan could be omitted when output RMS power is moderate.
